Can I make an assumption that the trains left at the same time (irrespective of the time zones for Chicago (Centrtal) and New York (Eastern)?

yea

radar · Answer

O.K.  They will meet when their individual distance traveled sums up to 1,000 miles.

radar · Answer

Their distance is equal to their speed times the time.
Chicago train d=40t
New York train d=60t
40t+60t=1000
100t=1000
t=10 (hours)
ten hours, they will meet, I am hoping they are on different tracks!
